Tiny blue chalcedony and Sterling Post Earrings

I have been trying to "work small" lately, and these tiny stones were at about the limit of my ability. The pretty blue chalcedony cabochons measure 4mm x 6 mm, but would not fit in pre-made settings. I fashioned oval tube settings in sterling to complement the stones.  The earrings with setting measure about 5mm x 7mm. Sterling posts and ear nuts.
